Science of Shadows

Thomas ZurbuchenSpace Science Directorate, NASA

From studying the solar corona to providing precise measurements of the orbit of an object in deep space, scientists continue to develop new uses for eclipses nearly every year. And with the recent total solar eclipse across the United States, scientists and non-scientists alike have been captivated by the knowledge gained when one astronomical body passes in front of another. However, eclipses are not unique to Earth, the Moon and the Sun; similar phenomena, called transits or occultations, occur between different stars, planets and moons. On occasion, these events can be seen from Earth (with the help of telescopes and other instruments) or by satellites. During this talk, we will first review the 2017 total solar eclipse through the eyes of NASA. We will then discuss how eclipse-like events are being used to study bodies within our solar system as well as discover worlds beyond.
